Article Received on 26/05/2020 Article Revised on 16/06/2020 Article Accepted on 06/07/2020 ABSTRACT Background: The nuchal cord is described as the umbilical cord around the fetal neck. It is classified as simple or multiple, loose or tight with the compression of the fetal neck. The term nuchal cord represents an umbilical cord that passes 360 degrees around the fetal neck. Objective: To find out perinatal outcomes in cases of labour of babies with nuchal cord and compared with other cases without nuchal cord. Patient and Methods: The prospective case-control study was conducted in maternity teaching hospital centre in Sulaimani / Kurdistan Region of Iraq, from June 2018 to April 2019. Cases of study divided into two groups. First group comprised of women in whom nuchal cord was present at the time of delivery they were labelled as cases. Second group was a control group composed of women in whom nuchal cord was absent at the time of delivery. Results: This study included (200) patients, (100) women with nuchal cord in labour. (59%) of the cases of nuchal cord in age group (20-29) years, (40%) of them were primigravida, delivery modes for women with nuchal cord were mainly normal vaginal delivery (76%) and cesarean section (24%).

  • Low-Lying Placenta
    LOW- LYING PLACENTA LOW-LYING PLACENTA WHAT IS PLACENTA PRAEVIA? The placenta develops along with the baby in the uterus (womb) during pregnancy. It connects the baby with the mother’s blood system and provides the baby with its source of oxygen and nourishment. The placenta is delivered after the baby and is also called the afterbirth. In some women the placenta attaches low in the uterus and may be near, or cover a part, or lie over the cervix (entrance to the womb). If it is shown in early ultrasound scans, it is called a low-lying placenta. In most cases, the placenta moves upwards as the uterus enlarges. For some women the placenta continues to lie in the lower part of the uterus in the last months of pregnancy. This condition is known as placenta praevia. If the placenta covers the cervix, this is known as major placenta praevia. Normal Placenta Placenta Praevia Major Placenta Praevia WHAT ARE THE RISKS TO MY BABY AND ME? When the placenta is in the lower part of the womb, there is a risk that you may bleed in the second half of pregnancy. Bleeding from placenta praevia can be heavy, and so put the life of the mother and baby at risk. However, deaths from placenta praevia are rare. You are more likely to need a caesarean section because the placenta is in the way of your baby being born. HOW IS PLACENTA PRAEVIA DIAGNOSED? A low-lying placenta may be suspected during the routine 20-week ultrasound scan. Most women who have a low-lying placenta at the routine 20-week scan will not go on to have a low-lying placenta later in the pregnancy – only 1 in 10 go on to have a placenta praevia.

  • The Effect of Nuchal Cord on Perinatal Mortality and Long-Term Offspring Morbidity
    Journal of Perinatology https://doi.org/10.1038/s41372-019-0511-x ARTICLE The effect of nuchal cord on perinatal mortality and long-term offspring morbidity 1 1 2 1 Roee Masad ● Gil Gutvirtz ● Tamar Wainstock ● Eyal Sheiner Received: 28 May 2019 / Revised: 11 August 2019 / Accepted: 16 August 2019 © The Author(s), under exclusive licence to Springer Nature America, Inc. 2019 Abstract Objective To evaluate perinatal and long-term cardiovascular and respiratory morbidities of children born with nuchal cord. Study design A large population-based cohort analysis of singleton deliveries was conducted. Maternal and birth char- acteristics, as well as cardiovascular and respiratory morbidity incidence were evaluated. Kaplan–Meier survival curves were used to compare cumulative hospitalization incidence between groups. Cox regression models were used to control for possible confounders and follow-up length. Results 243,682 deliveries were included. Of them, 34,332 (14.1%) were diagnosed with nuchal cord. Perinatal mortality rate was comparable between groups (0.5 vs. 0.6%, p = 0.16). Kaplan–Meier survival curves demonstrated no significant p = p = 1234567890();,: 1234567890();,: differences in cumulative cardiovascular or respiratory morbidity incidence between groups (log rank 0.69 and 0.10, respectively). Cox regression models reaffirmed a comparable risk for hospitalization between groups (aHR = 0.99 (95% CI 0.85–1.14, p = 0.87) and aHR = 0.97 (95% CI 0.92–1.02, p = 0.28). Conclusions Nuchal cord is not associated with higher rate of perinatal mortality nor long-term cardiorespiratory morbidity. Introduction Controversy exists in the literature regarding the sig- nificance of nuchal cord.
